I needed a new blade and the Bolt-Blade head was about rounded off.
Simply, unplug the spark plug, turn the mower over with the oil fill facing down. Put a block of wood by the blade to keep the blade from spinning. I used a 5/8 socket and took the Bolt-Blade nut off. Replaced the blade and squirted some oil on the Bolt-Blade as I tightened the bolt.

Traction cable broke, and mower blade was due to be replaced.
1. Tipped the mower over and removed the blade nut note use a block of wood to hold blade steady. And the two cover plate mounting bolts to cable housing.
2. Install new blade using the same mower bolt. Don't forget to use the block of wood to hold blade steady.
3. Turn the mower right side up and install new cable. Run spring clip through housing and attach, and push black plastic clip through housing until it clicks into place. Run cable up through cable housing and run S clip into throttle housing. Note don't tighten cable until you have run cable through brackets and loop harness. Once installed you can tighten mounting bolt( my model has one bolt on the left hand side of mower handle bar that also holds the throttle lever)
4. Turn mower on it side again and install the two cover plate bolts from underneath and tighten. Total time for both installs 20 minutes.
One other note tip the mower on its side with gas tank facing up or you'll have a gas puddle on the ground.

Lawn Mower cutting poorly and would not pull as belt was dry rotted.I had lost the old chute and tired of emptying the bagger every 40 feet.
Unbolted appropriate bolts holding belt cover and replaced belt. The guide is held on by two bolts and the belt cover on top of the mower is held by two screws from the bottom. You have to do all work from the bottom of the mower. So have something to lean the mower on so you can access bottom without emptying the gas and oil.

    Perfect fit for my Toro cordless battery electric start lawn mower
    Ordered new blade & side discharge cover for a 2015 mower. Both were a perfect fit making my job much easier with a one swipe cut for a perfect groom. Couldn't be happier with my purchase.
